We are doing synthesizer and longing for Professor Sakamoto.
That there is no “VOCO” from once in a while because it is doing just drum.
Professor says that recalls, but the tone change is busy anyway.
I would easy if you driving in advance a program change,
It does not do it by following the professor at the time.

The Roland MC-4 MicroComposer was an early microprocessor-based music sequencer released by the Roland Corporation. It could be programmed using the ten key numeric keyboard or a synthesizer keyboard using the keyboards control voltage and gate outputs. It was released in 1981 with a list price of US$3,295 (¥430,000 JPY) and was the successor to the MC-8, which in 1977 was the first microprocessor-based digital sequencer.

This sequencer was released before the advent of MIDI, and viewed by some composers to have more accurate timing. The MC-4 has an output patchbay to the right of the control panel, allowing you to patch the MC-4 to a synthesizer using 3.5mm patch cords. There are four channels of outputs containing CV-1, CV-2, Gate and MPX (multiplex) to control four separate synthesizers.To the left of the output patchbay there are two switches and a control knob. The control knob alters the tempo of the sequencer. The first switch is for cycle mode (which allows the programmed sequence to repeat continuously until the sequencer is stopped), the second switch is for sync control. The MC-4 can be synced to other Roland equipment such as a drum machine or another MC-4 MicroComposer (offering eight separate channels of sequencing).

Logic System is the musical project of Hideki Matsutake who was the sequencer and synth programmer for Yellow Magic Orchestra between 1978-1982, often referred to as their fourth member. Before this he was the apprentice and later assistant to electronic ‘space music’ composer Isao Tomita.

Inspired by Wendy Carlos’ album Switched On Bach, Matsutake started out in the industry arranging and programming for albums of Moog-ified popular songs (including a Beatles album), which were gaining popularity during the 70’s. He was involved in the production of various releases from pop/new wave artists in Japan (and for each member of YMO’s solo careers) throughout the 80’s, and he somehow found the time to begin to record his own output in 1981 under the name Logic System.

The iOS application – which is named “TANSU (dresser)”, is a miniature
version of a Modular Analog Synthesizer. This synthesizer is the same as the
one used and mastered by Hideki Matsutake of LOGIC SYSTEM.

The sounds that were sampled and used for the VCO (Voltage Controlled
Oscillator) come directly from the actual “TANSU” owned by Hideki Matsutake
himself.
In addition, it also contains many original LOGIC SYSTEM recordings. The
application condenses the fun, experience and sound of an actual modular
synthesizer onto the small screen of an iPhone!!

What will the sound be like when using the application? This application is
focused on providing the user with the feeling and excitement of using the
actual synthesizer for which it is based.

Not only for a techno fan, but for any music lover!! Feel what it is like to
create your own music!!
Try this application to experience the “the birth of sound and music.”

Enhance the basic functionality of an analog synthesizer. (Various sound

processing is possible.)

2 channel 8 step analog sequencer!

Connect patch cord to create original sounds

Three sound sources can be mixed by a three-channel mixer

Note: TANSU has a major downside because of it used of sampled material. The developer notes “Commercial use of the works created by using this application is subject to the copyright clearance from right holders.”
